Halogen GU10 spotlights were banned in 2016 but other halogen bulbs got a stay of execution as manufacturers argued LEDs weren’t a viable replacement due to higher costs.

The E27 Edison Screw, B22 Bayonet Bulb and the smaller E14 and B15 are now included in the ban.

However there are a few specialists’ bulbs, where LED or other energy-efficient alternatives are not available, which are exempt from the ban.

These include G4, G9 and R7 bulbs, which are used in some ovens and cooker hoods.

The ban sees the final stage of a European Union directive (EC 244?2009) that has progressively banned less efficient light sources, with the aim of improving energy efficiency and cutting carbon emissions.

These rules will remain relevant for as long as the UK follows EU legislation but manufacturers have indicated they are unlikely to produce halogen bulbs specifically for the UK after Brexit.
